Sheet Metal Fabrication

Spot Welding

High-quality, cost-effective spot welding sheet metal performed on-site.

High-Quality • Precision Craftsmanship

In-House Spot Welding Sheet Metal

With over 50 years of industry knowledge, GTR Manufacturing’s spot welding department bring their skills and experience to every custom job. Although sometimes considered a “simple” method of welding as it does not require the finesse that TIG or MIG welding does, our team’s attention to efficiency, detail, and cost means we can create high-quality custom parts on any of our four welding stations at a competitive price.

Spot welding, or resistant spot welding, is one of the most common forms of welding used in the precision sheet metal fabrication industry. It’s considered a sheet metal fabrication “staple.” Spot welding allows flat materials to be connected without the need to rivet or screw the materials together. Instead, two metal surfaces are joined by the heat obtained from resistance to electric current. Two shaped copper alloy electrodes concentrate the welding current into a small “spot,” fusing the materials together.

Spot Welding Benefits

Spot welding sheet metal with GTR Manufacturing allows our customers to:

  • Combine different materials without distortion or warping
  • Solution for difficult welds on thin materials
  • Reduce cost and save time

Engineering & Design Support

GTR Manufacturing’s experienced engineering department can provide concepts, design changes, product enhancements, and reverse engineering. We will work with your team to deliver your parts at competitive costs.

Our sales, management, and engineering teams have experience in a wide range of industries and understand their changing needs. We work in close partnership with our clients in developing and refining product designs and production process planning to simplify manufacturing and create cost savings for your end product.

We have the capability to import and unfold your 3D models ( .dwg, .step, .iges, .sldasm, .ldprt, .dxf) built in Solid Works, Pro/E, and other modeling software. The model is unfolded and downloaded directly into the CAM process, reducing errors and assisting in short lead times for your sheet metal parts.



By using the Just-In-Time (JIT) inventory strategy, GTR Manufacturing schedules production to meet your ordering needs. We reduce costs by carrying less idle inventory, resulting in a quality product that is delivered on time at a lower price.

We pair JIT with the Kanban technique to manage our highly-efficient development process. We establish minimum and maximum quantities, fulfilling customer needs on a pull system. This method empowers us to reduce inventory for customers and suppliers and uses lean production practices. In addition, we have full insight into your pipeline through an online portal, ensuring it’s always full.

Is GTR’s Spot Welding Service Right For Your Next Project?

  • Is your business in need of welding that adheres to specific requirements?
  • Have other manufacturers looked at your blueprints and ruled that your systems are “too difficult” or complicated to create?
  • Are you looking for a straightforward job but are surprised at how long the lead times are?

We are proud to simplify the precision sheet metal manufacturing processes by offering spot welding as part of our one-stop-shop capabilities to speed up project timelines and lower the risk associated with relying on external supply chains. With complete oversight and control over the entire production process—from prototyping to shipping—GTR ensures uncompromised, on-time quality and delivery.
